#IndianaJones and the Kingdom of the Crystal Skull,
#StevenSpielberg was not on board with its big science fiction twist according to George Lucas:
"I said, 'Steven, this is perfect because it’s the 1950s, when flying saucers were a whole thing,' but he said 'no.' We did about five scripts, and finally Steve and I compromised: 'Look, what if they’re not aliens but from another dimension.'"
